I'm a full-stack developer who builds complete web apps and SaaS products in Next.js, React and TypeScript — not just the front end, but the whole thing: authentication, Stripe payments, databases and deployment.
Recently I built and launched Atlas, a full fitness SaaS, on my own — plus a Shopify app and a WordPress plugin, so I'm comfortable right across the modern web stack.
If you've got an idea you want turned into a working, production-ready product, send me a message and tell me what you're building. I reply fast.

FAQ
Do you provide hosting for the custom app?
I can deploy the app on your preferred hosting provider (like Vercel, Heroku, or AWS) and help you set it up. The hosting costs are not included in the Gig price.
Can you integrate a third-party API into my Shopify store?
Yes, absolutely. I specialize in backend integrations (Node.js) and can connect your store with almost any external service that has a REST or GraphQL API.
Will my app be public or private?
This Gig is primarily for custom apps built specifically for your store. If you want to build a public app for the Shopify App Store, please contact me first so we can discuss the strict Shopify approval requirements.
